Clay pot saucers look innocent enough but they can bring a slow agonizing death to patio plants. The problem happens during prolonged periods of heavy rain when is retained in the saucers. As a result the compost remains soaking wet and starved of air, and the plant roots slowly rot.
To protect your plants from waterlogging, fill the saucers with gravel so the plant roots won’t have to sit in water. Better still, use pot feet or bricks to keep the container above ground level.
Other common causes of waterlogging are containers without drainage holes or drainage holes become blocked. This is why you should always use a crock (piece of broken pot) or a stone to cover the holes before planting. Putting gravel in the bottom of the pot is a good idea for taller plants, as it will add stability as well as improving drainage.
